A1 connected to the arm 21 as 38, 41 3, and 45 for the plupose of pulling parallel t to its"1'11itia1 position after 11 an 1 of t e e rods re shown as ranged 0 each other and a1] onnected by crank] ers 46t corresp ndin seri of rods 47 extending transversely of the of push rods 51 extending substantially parallel to the steering column 52 and having their upper portions slidable through a guide plate 53 shown for convenience as arranged under the hand controlling or v, steering wheel 8, said rods being provided at their upper extremities with heads or buttons 54 to enable the operator to press the push rods 51 downwardly.. In addition to the rods 51, an additional push rod 55 is provided, the same being arranged in parallel relation to the other rods and mounted I in the same manner and being used as will hereinafter appear for releasing themultiple latch and bringing the gearing back to a neutral condition. Each of the rods 51 is connected to its bell crank lever 50 by a cam face 63 on the latch 59 so that as. any

sliding. joint in connection with which a compensating spring 56 is employed so'that in case the operator depresses one of the rods 51 too' far, it will have no serious eflect on the other connections described.

Each of the push rods 51- is provided with 'a stop shoulder 57 adapted to be engaged by the bottom face 58 of a multiple latch'59 held yieldingly toward the series of push rods 51 and by means of a coiled expansion spring 60 mounted in a'combined guide 8, said guide and housing being provided 7 with lugs 61 to secure the same in fixed relation to the frame of the machine. Each of the push rods 51 and 55 is further provided with an inclined or cam shoulder 62 adapted to coiiperate with a corresponding rod 51 01-55 is depressed, the latch 59 is shifted so as to release any other rod which may have previously been engaged and held downwardly by said latch.

64 designates a bracket which supports the shaft 65 on which the bell crank levers 50 are mounted to turn.

66 represents a foot lever'which is fast on a rock shaft 67 having fast thereon a bevel gear wheel-68 which meshes with another bevel gear wheel 69 fast on the adjacent end of the clutch operating shaft 25 as shown in Figs. 1 and 2. The upper portion of the lever 66 is provided with a rack face or teeth 70 adapted to be engaged and held by a spring catch 71-shown as mounted in a casing 72 secured to the floor member 10.

- 7 3 designates a pedal which is pivotally mounted at 7 4 on the lever 66 and provided with a trip arm which by rocking the pedal 73 in the proper direction operates against the point of the catch 71 and forces the same out of engagement with the teeth wheel A. to the 'tion,

66 to be retracted under the action of the springs 24 (see Fig.3), which act on the straps'22 and thereby on the eccentrics 23 to turn the shaft 25 back to its, initial or neutral position.

ously-shift the fork which controls the lock-' ing device for the clutch e by means of the arm 39, it being remembered-that the. arms 40 and 39 are both simultaneously operated by the same rod 41. The operator then depresses the foot lever 66 thereby turning the clutch operating. shaft 25 and locking the gear E to the shaft 4 andthe gear A to the shaft 6. The motion of the shaft 4 is now transmitted through the gears E and F to the countershaft 15 and then through the gears B and A to the shaft 6. The machine is now in what is known as low speed. Inthe same way the operator throws the machine into secc'md speed by depressing the proper button 54 so as to lock the shaft 4. The drive is then from the shaft 4 through the wheels C and D, the countershaft E and the wheels B and A to the shaft 6. To obtain high speed or direct drive, the proper button 54 is depressed, thereupon connecting the. shaft 4 directly to the shaft 6 by means of the clutch 0 Reverse gear is efle'cted by operating the clutch 01 thereby locking the wheel G to the shaft 4. The drive is then from the shaft 4 through the gears G, I and H to the countershaft 15 and then through the gears B and A tothe shaft 6. To throw the gearing into neutral or inoperative condithe operator depresses the rod 55 which merely has the effect of tripping the multiple latch 59 and allowing the previously depressed rod 51 to move back to its initial position. operation of the transmission gearing and operating means therefor is extremely simple. All the operator is required to do is to several groups in the transmission case are always in mesh whether idle or working and As'a whole, the construction and that the gears of the shafts 4 and 6 are taken up gradually without any jerking motion by the engagement of the clutches a, b, c, d

and 6. When in high speed, all of the gears both on the shafts 4 and 6 and on the shaft jured as in the case of the present day gear shifting construction in which certain of the gears are shifted into and out of actual mesh every time a different speed is desired. 7

What I claim 'is: 1. Transmission gearing embodying, in combination, a driving shaft, a driven shaft in longitudinal alinement therewith, a counj tershaft parallel to said driving and driven shafts, changeable speed gears on all of said shafts arranged in groups, the gears on the countershaft being fast, and the gears on the driving shaft being normally loose and always in mesh with the,gears on the countershaft, a clutchfor locking each driving and driven shaft gear to its shaft, a clutch op- I crating shaft parallel to said driving and driven-shafts, a series of clutch operating 'ture in presence of menace eccentrics normally loose on said clutch operating shaft, manually controlled means for selectively locking said clutch operating.

in longitudinal alinement therewith, a countershaft parallel to said driving and driven shafts, changeable speed gears on all of said shafts arranged in groups, the gears on the countershaft being fast, and the gears on the-driving shaft being normally loose and always in mesh with the gears on the countershaft, a clutch for locking each driving and driven shaft gear to its shaft, a clutch operating shaft parallel to said driving and driven shafts, a series of clutch operating members normally loose on said clutch operating shaft, manually controlled means for selectively locking said clutch operating members to their shaft, means for turning said clutch operating shaft, push rodsfor selectively shifting said locking means, and a multiple latch common to and for all of said rods and adapted to be trippedby one of said rods. y In testimony whereof I afiix my signatwo witnesses.
